Description

Building active lighting and ventilation skin unit

technical field

The utility model relates to a building lighting and ventilation component, in particular to an active lighting and ventilation skin unit.

Background technique

At present, the contradiction between the supply and demand of conventional energy has become increasingly prominent, and building energy consumption has become one of the three major energy consumers in my country. Building energy consumption mainly refers to the operating energy consumption of civil buildings, such as providing heating, air conditioning, and lighting for residents. Common building lighting and ventilation components include casement windows, sliding windows and hanging windows, but these components cannot solve the problems of indoor glare and low illumination uniformity. The problem.

Most of the existing dynamic skins can only control the light environment, but not the wind environment. The reason is that if the dynamic skin that adjusts the light environment is used as a maintenance structure at the same time, it can only be closed in rainy and snowy weather or strong wind weather, thus blocking all ventilation. Therefore, the dynamic skin that adjusts the light is often located in the middle of the double-layer glass, or inside and outside the glass. To achieve indoor ventilation, it is necessary to manually open the opening fan of the glass. The dynamic skin that adjusts the wind environment is divided into two types: transparent and opaque. The translucent skin cannot adjust the indoor light environment, and the opaque skin can only block all the light in rainy, snowy or windy weather.

The system disclosed in the Chinese patent with the invention title of "a curtain wall decorative panel" includes a main panel, a plurality of ventilation holes are evenly opened on the main panel, and a disc plate is installed in each of the ventilation holes in a reversible manner. The shape and size of the disc plate are adapted to the shape and size of the ventilation hole. The invention installs a rotatable disc plate in the ventilation hole, and through the rotation of the disc plate, the amount of air intake can be effectively adjusted, wherein the disc plate can rotate freely in the case of wind, which greatly weakens the external wind pressure and improves the The dynamic decoration of the building curtain wall.
